The man involved in a standoff on Interstate 55 with law enforcement Sunday has been identified as the suspect in the death of a Martin, Tennessee, woman last week.

Eric Higgs, 46, was pronounced dead on the scene after leading police on a high-speed chase southbound in the northbound lane of I-55 near the Panola/Tate county line.

Authorities said he struck a vehicle, which caused an 18-wheeler and another vehicle to wreck as well.

Higgs was pinned inside his 2016 Audi sedan when authorities say he fired shots at police, who returned fire.

Higgs was wanted in the Wednesday morning death of his wife, Barbara Higgs, 48. Authorities said she was found dead inside a home in Martin after officers were called to the residence for a welfare check when she didn't show up for work.

The pursuit, which began shortly after 2 p.m. Sunday, involved Hernando and Senatobia police, Panola County deputies and a Mississippi Highway Patrol trooper.

An officer who has not been identified was grazed by a bullet or some shrapnel, but his injuries are said to be very minor.

According to the Mississippi Department of Transportation, the standoff happened around Exit 263 in Tate County. I-55 was shut down in both directions for a few hours, and traffic was diverted onto U.S. 51.
